A source of sound is moving along a circular orbit of radius `3 meter` with an angular velocity of `10 rad//s`. A sound detector located far away from the source is executing linear simple harmonic motion along the line `BD` with an amplitude `BC = CD = 6 meters`. the frequency of oscillation of the detector is `(5)/(pi)` per second. the source is at the point `A` when the detector is at the point `B`. if the source emits a continous sound wave of frequency `340 Hz`, find the maximum and the mnimum frequencies recorded by the detector.

A source of sound is moving along a circular orbit of radius 3 m with an angular velocity of 10 rad/s. A sound detector located far away from the source is executing linear S.H.M. along the line BD (see Fig. 14.4.13) with an amplitude BC = CD=6m. The frequency of oscillation of the detector is 5//pi per second. The source is at the point BA when the detector is at the point B. If the source epiits a continuous sound wave of frequency 340 Hz, find the maximum and the minimum frequencies recorded by the detector.

A source of sound emitting a frequency 660 Hz is moving counter-clockwise in a circular path of radius 2 metres with an angular velocity 15 rad/s. A recorder at a distance from the source is moving simple harmonically along a straight line with an amplitude 2 metres. The frequency of SHM is (15)/(2pi) per second. The arrangement is shown in figure. When the source is at point A the detector is at D. Find the maximum and minimum frequencies recorded. Velocity of sound in air at this temperature can be taken as 300 m/s

A sound source is falling under gravity. At some time = 0, the detector lies vertically below the source at a depth H as shown. If v is the velocity of sound and f_(0) is frequency of the source, then the apparent frequency recorded after t = 2s is

The figure shows the location of a source and detector at time t = 0. The source and detector are moving with velocities v_s = 5hati m s^(-1) and v_D = 10 hatj ms^(-1) respectively . The frequency of signals received by the detector at the moment when the source cros the origin is (the frequency of the source is 100 Hz . Velocity bof sound 330 m s^(-1) .)
